In this talk I will present a new result of J. Lehec about
regularization property of OU semigroup. Result of this type was first
established by K. Oleszkiewicz et al. but with dimension depending
constant.
The idea of R. Eldan and J. Lee was to apply tools from the stochastic analysis (such as change of measure) in order to remove the dimension dependence. Quite recently J. Lehec significantly improved the proof exposition and we detail the idea in order to encourage further studies in this direction.
